improvements to autoload regexen
many thanks to @Lompik
* don't match empty unit names. AIUI unit names are alphanumeric with
the exception of the group [-_.@], non ascii are backslash-escaped.
* more strictly match temp file names: .# prefix, [[:hexdigit:]]{16}
suffix. the filenames are a unit name with a unit suffix (systemctl
edit --full) or just override.conf (edit without --full option)
* add regex for dropin config files. This is just a file with ".conf"
extension, with the added constraint that it's a file having some
parent directory named "systemd"
